`active_response_id`；旧线性历史迁移成单一路径。响应 ID 预留阻止被取消或迟到的旧生成抢占当前分支。新接口 `POST /api/chat/conversations/{conversation_id}/messages/{message_id}/select` 用于选中版本；ChatRequest 的 `retry_message_id` 指定编辑或重新生成的原消息，列表响应 `versions` 给出同级版本 ID。 + +只读代码块复用编辑器字体偏好和主题代码色。纸间时光 1.9.1 将工作区的三色圆点、底部语言标记和阴影覆盖到聊天 Shiki 代码块；已安装主题需更新。字体大小、代码行号和换行仍由现有偏好控制。 + +回归：`tests/test_chat_versions.py` 验证编辑分支、回复再生成、版本切换、活动顺序持久化和迟到回复隔离；前端 ChatView/chat store 测试验证时间线顺序及重试上下文。 + +- 后端：`pytest tests/test_chat_retrieval.py tests/test_markdown_tools.py tests/test_chat_context.py tests/test_chat_history.py tests/test_agent_core.py -q`，使用隔离测试数据目录。 +- 前端：`npm test -- src/utils/usedCitations.spec.ts src/features/chat/ChatView.spec.ts`，然后 `npm run build`。 +- 手动：使用支持工具调用的 Provider，开启检索，提出需要多次查找的问题。确认补检索后继续生成、正文引用出现时才显示卡片，刷新对话后编号不变。模型自行决定是否需要补检索，并非每个问题都必定调用。 +- 智能体：允许上述新工具及 notes.read，以格式目录查询 → 生成片段 → 读取笔记 → 局部修改的顺序验证；在读取后人为编辑原笔记，确认过期修改被拒绝。 + +自动验证使用可控 Provider 流，不调用真实厂商或修改用户笔记。真实模型是否主动检索及引用质量需要单独验收。 + +## 聊天渲染与引用格式修正 + +检索工具向模型仅返回 `number`、`file_path`、`heading_path`、`content`，内部 `citation_id` 和定位字段只通过 Citation 事件交给客户端保存。系统提示词要求引用固定使用 `[1][2]`，在对应结论或示例说明旁标注，不重新编号，不把通用知识当作笔记内容。此约束减少格式漂移，不代表自动验证模型结论。 + +旧回答中的 `[cit_blk_…]` 按已保存来源 ID 映射为原数字编号，继续显示编号、标题路径与原文摘要卡片。正文数字也可点击定位同一笔记；未知 ID 不产生虚假来源，代码里的标记不视为引用。 + +工具调用前后的正文用空行分段。聊天代码块显示语言名称与复制源码按钮；Mermaid 支持源码/预览切换与复制。最终 HTML 净化保留 SVG foreignObject 中的标签，同时删除事件处理器，避免图中方框存在但文字消失。 + +验证方法：运行 `test_chat_retrieval.py` 检查模型工具结果不包含内部 ID、来源编号稳定及段落边界；运行 `usedCitations.spec.ts`、`markdownRendering.spec.ts`、`markdownDiagramRendering.spec.ts` 检查历史 ID、相邻数字引用、代码排除、语言标签、图中文字净化、源码切换和剪贴板原文。手动复查原有回答的卡片与正文编号均可定位笔记，新建检索问答使用数字编号。 + +聊天代码块改用包含工具栏与代码内容的统一边框容器。纸间时光 1.9.2 将装饰作用于整个容器，语言名称与复制按钮位于框内，底部保留语言标签。Shiki 行间分隔换行从显示 DOM 中移除，真实空行仍由 `.line` 保留，复制始终读取独立保存的原文。`markdownRendering.spec.ts` 覆盖容器、工具栏、空行及原文复制，防止重复行高回归。 diff --git
